Using this method a distance of max. 200 m is permitted, adding up the lengths of all 
cables from the converter to the last control unit in the network. For larger distances the 
use of fiber optics is recommended, alternatively signal amplifiers for the RS485 bus 
can be used.. 
When using fiber optics, the individual units are connected to each other up to the 
RS485/fiber optics converter using cables. The transfer to the remote office building is 
carried out by means of fiber optics and re-converting to RS485 or—if connecting di-
rectly to the PC—to RS232. 
Setting the network address is described in the “Setting the Address” chapter. 
 

5  Indicator Lamps 

 
A total of four LEDs are used to indicate various parameters of the control unit. 
Three of those indicators are internal and only visible after opening the housing. 

 
Caution: 
Before opening the housing, unplug the power supply to prevent short-circuits 
inside the control unit!!! 

 
With the LEDs, the correct operating voltage supply of both the electronics and the sen-
sors can be checked. In addition, there is an indicator showing whether the control unit 
actively participates in the data communication with a connected control computer.  
The fourth indicator is integrated into the housing and indicates the proper function of 
the control unit by cyclic flashing (1 second on/1 second off).
